Bitcoin is a digital and global money system currency. It allows people to send or receive xbt bitcoin wiki hardware across the internet, even to someone they don’t know or don’t trust.

Money can be exchanged without being linked to a real identity. The mathematical field of cryptography is the basis for Bitcoin’s security. A Bitcoin address, or simply address, is an identifier of 26-35 letters and numbers, beginning with the number 1 or 3, that represents a possible destination for a bitcoin payment. Addresses can be generated at no cost by any user of Bitcoin.

For example, using Bitcoin Core, one can click “New Address” and be assigned an address. It is also possible to get a Bitcoin address using an account at an exchange or online wallet service. One of the differences between using bitcoin and using regular money online is that bitcoin can be used without having an internet connection to link any sort of real-world identity to it. Unless someone chooses to link their name to a bitcoin address, it is hard to tell who owns the address. Each address has two important pieces of cryptographic information, or keys: a public one and a private one. A public key is what determines the ownership of bitcoins, and is very similar to an ID number.

If someone wanted to send you bitcoins, all you would need to do is supply them your bitcoin address, which is a version of your public key that is easier to read and type. For example, if Bob has 1 bitcoin at the bitcoin address “ABC123,” and Alice has no bitcoins at the bitcoin address “DEF456,” Bob can send 0. In the example above, “ABC123” and “DEF456” are the bitcoin addresses of Bob and Alice. But Bob and Alice each have a second key which only they individually know.

This is the private key, and it is the “other half” of a Bitcoin address. The private key is never shared, and allows the owner of the bitcoins to control them. However, if the private key is not kept secret, then anyone who sees it can also control and take the bitcoins there. Sites or users using the Bitcoin system are required to use a global database called the blockchain.
